iOS 7 MapKit MKAnnotationView's image property type encoding weirdness

Question

These are the results of

method_getTypeEncoding(class_getInstanceMethod(MKAnnotationView.class, @selector(setImage:)))
method_getTypeEncoding(class_getInstanceMethod(MKAnnotationView.class, @selector(image)))

7.0:

v12@0:4^{UIImage=#^vf{?=b1b3b1b1b1b16b2}}8
^{UIImage=#^vf{?=b1b3b1b1b1b16b2}}8@0:4

and 6.1:

v12@0:4@8
@8@0:4

I don't understand why it's a ^{... instead of @. It's causing me problems in Rubymotion.

Thanks in advance!
